AnnThe comments to "bring pressure to second ring" are probably not appropriate for your Magefesa model. These comments are appropriate forMagefesa Rapid II which has the pressure indicator very similar to the Kuhn Rikon Duromatic pressure cookers. Magefesa no longer sells the Rapid series in the US. My guess is you have their "Classic" which is a "developed weight" model which they are currently selling. You will need to get used to cooking by sound, I am sure your manual will tell how to tell if you are at full pressure. Basically at full pressure you should occasionally get a burst of steam from the pressureregulator in the handle of the cooker. The best way to do this is to take Guy's advice and only use water to familiarize yourself with the sound. Put some water, say a quart or so, in the cooker, close it, heat the water on high temperature until a steady stream of steam comes out of the pressure regulator. This is safe with no food in the cooker but not so safe with food in it. If you have a gas stove turn down the heat and let the cooker slowly come down in pressure until you get an occaional burst of steam from the pressure regulator. If you have an electric stove heat the cooker on one burner at high temperature and have another burner at low to medium heat and when the cooker reaches full pressure on the burner set at high move it to the other burner. You will need to do this a few times to familiarize yourself with the sounds and you will soon recognize when the cooker is nearing full pressure and how far to turn down burner temperature to maintain full pressure. In no sense is this type of cooker defective, it just gives you different signals of when nearing full pressure and when full pressure is being maintained and these signals are primarily audible, visual as with a Kuhn Rikon or a Magefesa Rapid. You will of course see steam coming from the regulator but this should not be the primary signals you look for.

Again do this familiarization with only water and you should take the cooker through several cycles to get to full pressure and maintaining full pressure.
